Question

question 10
the total amount of chemical energy that remains after autotrophs use some of the energy to fuel their own metabolism is known as
○ gross primary production
○ negative secondary production
○ positive primary production
○ net primary production
○ secondary production

Explanation:

Gross primary production is the total energy produced by autotrophs. Net primary production is what's left after autotrophs use energy for their metabolism. Secondary production is related to heterotrophs. There's no such thing as negative secondary production or positive primary production in this context.

Answer:

net primary production
